Homozygous, Heterozygous 1. An organism that has two identical alleles for a particular trait, Ex: HH or hh is ______ , while an organism that has two different alleles for a particular trait, Ex: Hh is ______ Back to the Game Board 10 Point Question

Codominance When offspring express two alleles for a particular trait at the same time. Ex: Black X White = black & white stripes Back to the Game Board 20 Point Question

Incomplete Dominance When offspring express a trait that is an intermediate or blend of two parents, because one allele for a gene is not completely dominant over another. Ex: red x white = pink Back to the Game Board 30 Point Question

X-linked or Sex-linked traits Traits that are carried by a gene on the X chromosome Back to the Game Board 40 Point Question

Phenotype The physical appearance or physical expression of an organism’s alleles. Ex: tall or yellow Back to the Game Board 10 Point Question

Genotype The gene (or allele) combination of an organism. Ex: Tt, TT, tt Back to the Game Board 20 Point Question

Several codons can code for the same amino acid Why do certain mutations have no effect on the amino acid sequence created in protein synthesis? Back to the Game Board 30 Point Question

Red flower parent is RR White flower parent is rr A red flower parent was crossed with a white flower parent to produce all red flowers in the first generation. If two red flowers from the first generation were crossed to produce a 3: 1 ratio of red to white in the second generation, then what is the genotype of the original parents? Back to the Game Board 40 Point Question

Frameshift mutation Insertions and deletions are the two types of this kind of mutation. Back to the Game Board 10 Point Question

Silent mutation Mutation that causes no change in the amino acid sequence. Back to the Game Board 20 Point Question

Nonsense mutation A mutation that results in a premature stop codon. Back to the Game Board 30 Point Question

Missense mutation A mutation that results in a change in the amino acid sequence. (one amino acid is changed) Back to the Game Board 40 Point Question

Genotypes /alleles of parents Genotypes of offspring Possible offspring results from the parents (these are possible-not guaranteed- results of a cross) List 3 things that punnett squares can show us. Back to the Game Board 10 Point Question

Genotypes= 1 SS, 2 Ss, 1 ss Phenotypes= 3 short hair, 1 long hair In cats short hair (S) is dominant to long hair (s). Cross a heterozygous short hair cat with a heterozygous short hair cat and provide genotype and phenotype ratios of offspring. Back to the Game Board 20 Point Question

Genotype= 100% Ss Phenotype= 100% short hair In cats short hair (S) is dominant to long hair (s). Cross a homozygous dominant short hair cat with a long hair cat and provide genotype and phenotype ratios of offspring. Back to the Game Board 30 Point Question

Back to the Game Board 40 Point Question

47 XX+13 What is the notation for the karyotype to the left? Back to the Game Board 10 Point Question

-Determine if/how a trait can be inherited -if it is dominant or recessive and -if it is x-linked or autosomal List three ways that a pedigree chart can be used Back to the Game Board 20 Point Question

heterozygous Shaded in= affected with Albinism. Is individual II-1 homozygous or heterozygous for normal pigment? Explain. Back to the Game Board 30 Point Question

No, because the mom is homozygous recessive and passes on one albino allele. Are any of the offspring for individuals I-I and I – 2 homozygous for normal pigment? If so , which ones? Back to the Game Board 40 Point Question

Normal gene sequence: T-G-A-G-G-T-C-C-T-C Mutated gene sequence: T-G-A-G-G-T-C-A-C-C-T-C Identify the type of mutation! Point mutation (substitution)
